I really like where you’re going with this story. Also, on the Day of Light, does Raven have to forgo cultivation? When she was in the temple with her parents, it seemed like the energy was distributed based on the number of spirit connections.

Yes, in that specific temple it would be better to be the solitary person there, but she can leave her brother in hers and disguise herself to enter one of the lower-populated public ones at the school. She could alternate the temple every year to avoid suspicion. Or, she could have her brother follow one of the advanced students, who has the lowest connections, into their room and hide in the corner so that both of them would get a decent private temple experience.
